b all w71 om it maconcern Be it known t at I, SIMON B. S'ronnn, of Syracuse, in the county of Onondago, in the State of New York, have invented new and useful Improvements in Recording Instruments for Wattmeters, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in recording instruments for wattmeters, in which the record or reading sought is derived from or dependent upon the speed of a revolving element.

The broad object is to automatically make a graphic record of-the number of revolutions or average speeds of a revolving element at regular periods during predeten mined intervals of tine.

The specific object is to make graphic records of the average rate of consumption of electric energy during predetermined periods of time, as for instance, each minute during a longer interval, as one day or week so that during such interval a series of records will have been made showing the a vcrage speeds or the number ot revolutions of the revolving part during the predetermined periods of time, and when used in connection with the revolving part of a nattmeter gives an exact record of the average rate of consumption of electric energ or kilowatt hours, during such periods ani interval ot time, as distinguished from the ordinary line drawing of a recording watt meter which indicates momentary luctuations and instantaneous values in load. In other words, I have sought to provide an instrument operated by one of the revolving parts of a watt meter or other instrument to record the average or relative Speeds or rate of consumption of electric energy for regular periods of a predetermined interval. of time. f

Other objects relating to the specific structure of my invention will be brought out in the following description.

In the drawings- Figure l is an elevation of my improved recording instrument showing the electrical connections diagrammatically. Figs. Q and 3 are respectively top plan and side elevation of Ithe device seen in Fig. 1, omitting the clock mechanism and electrical connections.

Fig. 4 is an end View of the record inder showing a modiied recording dei ce by which an iml'iression is made upon the record sheet at the end of each interval of .time instead of by a line, as shown in 1, 2 and 3. Fig. 5 is a side view of the cylinder shown in Fig. 4, showing the record produced thereby."

The device shown in Figs. l to 3 inclusive is especially adapted for use in connection with a revolving element, as W--A.-, of an integrating watt meter -M, and comprises essentially a, clock rotated recordicylinder -1-; an impression making device, as a marker -2- movable back and forth at regular predetermined intervals along the record cylinder -1- and adapted to make impressions thereon, and suitable mechanism. actuated by the revolving element for actuating the marker The record cylinder -l. i: preierably mounted on a vertical axis having its lower end stepped in a suitable bearing MEM and its upper end journaled in. a bearing M- of a frame Jii Rotary motion is imparted 'to the oy" der -1 through the medium oi an;i able chronometer, as a clock train m6@ ad worm gears Jimconnecting said clock, train to the upper end of a shaft or spin-:lle --8 oi' the record cylinder. The moww ment of the record cylinder is, therefore, synchronized with thc chronometer to make one complete revolution in a given period, as in this instance, one calendar weeh ot time.

The recording finger --i3-- is normally in a certain position relatively to and preterably near the lower end ot' the cylinder 1- and is moved upwardly alor `he cylinder with the same or varying 1 cgi-eel., ot' speed, according to the speed of operation of the rotary meter element --A--, such movement coi'itinuing through a predetermined interval, as in this instance, one minnte of `time so that if the speed of the driving element A varies, the degree et' npward movement of the linger -2- during each minute interval of time will corre-l renter than that, for any other same -15# and belts "-19- and the meeting of the shoulder -23- `and returning ledge -24- but the complete return movement of this belt -25- is quite immaterial owing to the fact that the upper ends of the line only are of service in obtaining the average consumption of electric energy or the average speeds of revolution of the driving element for given periods of time.

The .means for shifting the rollers. and belts 19- alternately into engagement with the opposite faces of the driving roller --1-i preferably consists of a pair of solenoids or electromagnets 33u having their plungers connected by rods 341- to oppositel sides` of the upper end of the oscillatory frame -17-, the winding of said solenoids beingelectrically connected to-'a source of electric energy, as a battery 31-.

The lsolenoids are connected in separate circuits deriving current from the same source as the battery 3land having terminal brushes -35 which bear upon diametrically opposite faces of a rotary commutator -36- hayingwai Single Contact terminal common to both circuitsf" flhe commutator --36- is -in this insta-nce rotated one complete revolution every two minutes through the medium of gears -38- which are driven by the ohronometer -6- so that the solenoids -33- are alternately energized every minute, or at each lating element -17 in one direction to force one of the rollers --15- and its .belt

-l9-- into contact` with the continuously rotating drivingroller -14-, Whereu on 'linear' motion is immediately .impart .td the belt '-19- causing the shoulder 2B- to ,engage the ledge 24-- and operate the belt w25-w1 and recording finger -Qfcar- A ried thereby, the recording finger continuing. its movement along the record cylinder -,-1- until the contact piece S7- establishes electrical connection with the other brush -85-, whereupon the opposite solenoid is energized and immediatelv operates to shift the oscillating frame -li'- in the opposite direction, thereby bringing the other roller -15- and its belt v-19- into engagement with the driving roller M14-L and allowing the first named belt -19- to return to its starting position by means of its counters/'eight -22-- As the frame --l'fw is shifted .in opposite directions it is held in its adjusted position by a suitable spring detent -40- bear ing upon a Vshaped lug -4l--, as best -secn in Fig, l.| said spring being tensioned the roller -15- and its belt -19- against the driving rollerl-li-e,- thereby establish-- ing a more positive drive for the belts -19- and -25-. 1

The gears -38- and commutator -36- are shown as driven 'from the second hand spindle as 44- of a clock-mechanism but it is obvious that any other chronometer 'controlled mechanism may be employed 'to The marker finger -45-- is substituted for the recording finger 2- shown in Figs. 1, 2 and 3 and is actuated by the belt -25 along the cylinder -1- in the same manner except that it does not contact with or make an impression upon said cylinder until, it reaches the limit of each up stroke `Wlrereupon it is automatically forced into engagement witl'` the`1ecoi'd cylinder by electrical energized means as thesplunger of a solenoid -48- which is connected in the switch between the battery -31-' and commutator -36-, said plunger having a vertically elongated bar -48'- which extends along one side of the cylinder so asto engage and operate the marker L15- in'anyI position.

In Fig. 5 I have shown a` cylinder as provided with a'series 'of records in the form of dots or visible impressions ,-50- which have been made by the finger -45- such dots may be connected by a transverse line as shown thus producing a chart which' gives a graphic record of the' average rates of consumption of electric energy or kilo- Watt hours for predetermined periods as one minute of time.

The operation of this particular device,

.briefly described, is as follows; Atthe .be-

ginning of a minute one of the belts -19` is thrown into contact with the vcontinuously 'rotating driving element --14- by` means of its solenoid 33-. which is energized every second minute through the medium of a chronometer controlled switch as one of the terminals 5-, and the Aterminal 37eof the commutator -36. This causes the actuated belt -19- and the shoulder -23- to move at the same prof' portionate speed as the maindriving ele# ment or meter shaft -A- the shoulder w23- engaging the ledge Q/L and thereby imparting vto the' belt -25-- the same speed of movement which in vturn elevates the recording finger ,-2- or -.45 as the case may be along the record cylinder -1-. At the end ofthe minute-the loo izo

other'solenoid B3- .is energized by the action of the cbmmutator -36-. to shift -25- :L -gain elevates the recording linger .-2 or ,45- as the case' 4may be along the cylinder L which. is. continuously shifting its position, said recording finger leaving an impression upon the-record cyl. inder during or at the end of each upward stroke, or rather during or at the end of each minute, vthe height to i'vliicli said recording finger moves during each minute period depending upon-tbe average speed of rotation or the number of revolutions of the main driving member -A`duning that minute period.
